Hart Island is a tiny and relatively unknown island in The Bronx which is home to at least 64,825 New Yorkers, all dead.

In New York City, there's a little-known island where as many as a million people are buried. It's a public cemetery for homeless people, stillborn babies and unclaimed remains. Visiting Hart Island is a challenge — even for families of the deceased, and now, some of those families are trying to change that.
